The best idea is still just to tokenize everything.

Each boss drops a CT Token, last boss drops 2. For 5 tokens you can buy a "bag of goodies" from the excavation team. The bag may contain some mythology tomestones, or a piece of random gear, or some gil, or a minion or whatever.

However that destroys the whole feeling of expectation on loot drops and that is most likely why it is not implemented.

The 1 loot per week but unlimited tries design, as far as I can tell, seems to be keeping CT alive. Yes many people feel forced to run the place over and over, but it also means that I could get a party together reasonably fast even on Mondays. Back in WoW when they implemented the loot lockout where you only ever see one item "drop" from each boss per week (i.e. if it doesn't drop something you want, that's still the end of it for the week), I heard people were having difficulties getting a raid together on the day before reset. The CT design improves on that quite nicely.
